UNITED STATES WILLIAM E. CRANDALL, OF NEV YORK, N. Y.

ROCKING-HORSE.

SPECIFICATION forming part of Letters Patent No. 326,721, datedSeptember 22, 1885.

Application filed January 24, 1885.

To all whom it may concern:

Be it known that I, WILLIAM E. CRAnDALL, a resident of New York city, inthe county and State of New York, have invented an ImprovedRocking-Horse, ofwhich the following is a full, clear, and exactdescription, reference being made to the accompanying drawings, inwhich- Figurel is a side View, partly in section, of my improvedrockinghorse. Fig. 2 is a crosssection of the same on the line xx,Fig.l. Fig. 3 is a longitudinal section on an enlarged scale of theparts that connect with the spring. Fig. 4 is an enlarged face View, andFig. 5 an enlarged side view, of the spring holding clamps.

This invention relates to a new rockinghorse in which a coiled spring isplaced directly beneath the center of the rocker to normally hold thehorse in the middle posi tion, thereby greatly facilitating the use ofthe toy.

The invention consists in combining a rocking-horse or rocking toy witha coiled spring, which is placed directly beneath the center of therocker-frame, and with certain holders for securing thereto the ends ofthe spring, as hereinafter more fully specified.

In the drawings, the letter A represents a suitable rocking-horse orother contrivance that is placed on rockers B B, which rest on the siderails a of a stationary frame, C. At the middle the two rockers B B areunited by a cross-bar, D, beneath which is a crossbar, E, which unitesthe two rails a of t-he stationary frame C.

F is a coiled spring, which is interposed be tween the two cross-bars Dand E and attached to them in manner hereinafter described, and which,when the parts are in the position shown by full lines in Fig. l, is inits normal condition-that is to say, the tension of the spring is suchas to draw the cross-bar D and hold the same directly over the crossbarE. When the person on the rockinghorse leans the same forward orbackward,as the case may be, the spring F is immediately distended, asindicated by dotted lines in Fig. 1, and being so distended tends toswing the (No model.)

horse back to its central position, theimpetus carrying the rockers overthe central position, when the spring is again distended, serving thusto keep the rocker in motion. It will be seen, therefore, that by usingthe single central spring,when the same is so constructed that it willbe distended whenever the horse is rocked, the labor of bringing thehorse back to its central position will be almost wholly assumed by thespring and taken oif the rider.

In Figs. 3, 4, and 5 I have shown in detail the means of securing theends of the spring F. For this purpose I employ two circular plates,band d,one for the upper and the other for the lower end ofsaid spring.Each of these plates has on its outer periphery a spiral thread forreceiving part ofthe coiled spring F. This spiral thread is clearlyshown at e, in Fig. 5. The plate b is riveted to a plate, f, which inturn is riveted or bolted to the under side of the crossbar D, and theplate d is riveted to a plate, g, which in turn is bolted or otherwisefastened to the upper side of the crossbar E. By this connection theends of the spring are securely held in place,and theplates b d, byengaging the terminal coils of the spring, hold the spring in propertension, as they prevent it from contracting or expandinglongitudinally.

In order to keep the rocker B in position on the frame C, said frame ison its outer sides provided with cheelcpieces h IL that iiank the sidesof the rocker, as shown in Fig. 2, and assist also in preventing thesingle coiled spring from twisting out of shape.

I claim nothing that is shown in Letters Patent Nos. 214,871, 304205,and 222,398.

I claim- The combination of the coiled spring F with thespirally-threaded circular plate b, plate f, spirally-threaded circularplate d, plate g, and cross-bars D E, substantially as herein shown anddescribed.
